It is not a straw man.
There is no amount of scrappy cleverness that gets you from zero to manufacturing cutting-edge chips without shitloads of capital investment, years/decades of R&D, a huge manufacturing workforce, and big contracts.
There's no such thing as starting small and scaling in that business.
You don't think $8.9B would do it?
This link contains a graph of fab costs over time. It looks like 9 billion might get you a cutting edge fab 15-20 years ago. but that's just the fab.

TSMC has already put $65B into the Phoenix fab and is adding at least that much more, so no. You're off by an order of magnitude.
TSMC's estimated costs in 2020, were $12 billion for their first fab. In 2025, their updated estimates were $65 billion for the first three fabs and $165 billion for when they get to six such facilities. So, $8.9B is a lot of money, but isn't anywhere close to getting to the equivalent to what TSMC has in Taiwan.

That wasn't the question. The question, at least for me, is can you build non-zero chip production, enough to start building out a sustainable business. Obviously you're not going to compete with TSMC on day one, but there's a wide spectrum between that and "garage".
